Infiniti engine problems

Owners have filed 1,309 complaints with NHTSA about the engine on Infiniti vehicles — 13% of everything reported about the brand, across 33 models. The model that accounts for most of them is the Infiniti G35, worst in 2003.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
